The Autonomic Nervous System
Captions available
The idea
The autonomic nervous system regulates involuntary activity in organs, glands, and smooth muscle.
In practice
Heart rate, digestion, and pupil size adjust continuously without anyone deciding to adjust them.
Where people slip
Involuntary does not mean unchangeable. Breathing and heart rate can be influenced indirectly.
